The goal of this research is to accurately model the aerodynamic forces and moments on a hypersonic vehicle. The accurate prediction of these aero loads is very important for the development of control algorithms for these vehicles. In addition to simply striving for accuracy, control algorithm design necessitates the force and moment prediction methodology also be computationally efficient.
Computational fluid dynamics (CFD)-based reduced-order models (ROMs) chosen for this work because they are both accurate and computationally efficient
Method in development is configuration-independent and has been used to model unsteady forces and moments of a sample hypersonic airfoil undergoing oscillations of the first three modes; consists of linear convolution combined with a nonlinear correction factor
Objective is to apply model to full three-dimensional hypersonic vehicle configuration and also investigate applicability to the transonic regime
